^^ That's the issue really isn't it.
It's no good to keep coming up with all the old tripe and lies about how hard it is to convict. The point is no one tries. The point is that you are ignored. The point is that police men assuming you are lying. The point is that no one gives a flying shit what violence men perpetuate, because it is fully acceptable and even gives them a status boost.
The problem is not evidence, so to keep going on about how hard it is to secure evidence is just ignoring the problem. The problem is male violence is normalised and acceptable, and women are expected to put up with shit. If men got the shit that we had to deal with regularly, it would be called war.
